What is the pOH of pure water at 60C?
pH = -log(concentration of H+ ion) which indicates acid pOH = -log(concentration of OH- ion) which indicates base In pure water at 25 degree Celsius, concentration of H+ and OH- is equal i.e. 10^-7 mol/dm^3 so, the sum of pH and pOH is -log(10^-7) + -log(10^-7) = 7 + 7 = 14
When you burn a log in the fireplace why is there a difference in mass?
The chemical composition of a log (and most organic substances) is carbon. Carbon when burned becomes oxides of carbon which are usually gases i.e. carbon dioxide and carbon monoxide. Therefore in essence, most of your log is being vaporized. If you were to burn the log in an enclosure such that none of the gases were lost, you would observe no mass difference.
What are observable changes with burning a log?
When a log is burned, observable changes include the transformation of the log's solid structure into ash and smoke as it combusts. The log changes color, often turning from brown or gray to black as it chars. Heat is produced, and gases like carbon dioxide and water vapor are released into the atmosphere. Additionally, the size of the log decreases as it loses mass through the combustion process.
Why people do not sink in saline water?
I think it is hard to swim under water in salt water because all of the salt is burning your eyes. It's just like being in a pool with too much chlorine in it. Thanks to the Holiday Inn I can't see good.
Can a log float above a water surface?
Yes, a log can float on water if its density is less than that of water. Logs are typically buoyant because they have a lower density than water, allowing them to float on the surface.
What are the properties of floating log of wood transported by water?
From the information you've provided ... that the log floats in water and is being transported by it ... the only properties that can be inferred are: -- The density of the log, in its aggregate entirety, is less than that of the water. -- The vertical dimension of the portion of the log below the water's surface is less than the depth of the water.
Why does a log of wood sink in water?
A log of wood sinks in water because wood is more dense than water. The density of an object determines whether it sinks or floats in a liquid. Since the density of wood is greater than that of water, the log sinks.
Is there gravity under water?
Definitely. A rock sinks in the ocean because gravity operates on it even under water. A log floats in water not because gravity stops under water but because the log's density is lower than that of the water.
Why does a log float?
An object will float on water if it has less density than the water. Or than any other liquid on which it is supposed to float.
Why does a large log of wood float on water but a steel needle sinks?
A large log of wood floats on water because its density is less than that of water, allowing it to displace enough water to overcome gravity and float. In contrast, a steel needle sinks because its density is greater than that of water, causing it to displace less water than its own weight and sink.
How can I protect my Myspace account from being hacked?
dont click on spams that will "log you off" to make u "log" back on. if that happends just exit the window && open a new one && log back on.
Can you tell why large log of wood floats on water but steel needle sinks?
Actually, the steel needle can float on water as well, so long as the surface tension is not broken. Answering the question, the buoyancy (ratio of density to that of displaced water) causes the log to float.
Are objects that sink are more dense than water?
Yes, the weight of the object doesn't matter as much as the density. For example, a pebble will sink in water because it is very dense, yet a log won't because it's not as dense as water.
What sport do men balance on logs in water?
log rolling, two folks on a log, they try to roll the log with their feet and get their opponent to fall into the water.
Will oak log float in water?
Yes if the density of the wood is less than that of water, no if the wood is high density (like ironwood) in which case it sinks. Even common woods like oak will sink uner the proper circumstances. There is a thriving industry on the Ottawa River in Canada salvaging sunken logs which have been underwater for more than a hundred years.
Why does a log sink in the water?
A log sinks in water because it is denser than water. The weight of the log pushes it below the surface of the water until it displaces enough water to create an equilibrium between its weight and the buoyant force of the water pushing back against it.
